[Haskell-beginners] using the current time

Excerpts from Torsten Otto's message of Tue Dec 08 18:18:54 -0500 2009:

Unfortunately, there is no way to "step out" of the IO monad:
once in the IO monad, always in the IO monad.

However, if you let time be of type IO String instead of String,
you can do:

    time = (liftM formatiereZeit) getClockTime

Where liftM :: (a -> b) -> m a -> m b, i.e. it converts
your function ClockTime -> String into IO ClockTime -> IO String.

Cheers,
